To enable this,

Enable

builder.Services.AddGrpc(options => {
    options.EnableDetailedErrors = true;
    options.MaxReceiveMessageSize = 6291456; // 6 MB
    options.MaxSendMessageSize = 6291456; // 6 MB
    options.CompressionProviders = new List<ICompressionProvider>
    {
        new BrotliCompressionProvider() // br
    };
    options.ResponseCompressionAlgorithm = "br"; // grpc-accept-encoding
    options.ResponseCompressionLevel = CompressionLevel.Optimal; // compression level used if not set on the provider
    options.Interceptors.Add<ExceptionInterceptor>(); // Register custom ExceptionInterceptor interceptor
});

Pr per service

Title

services.AddGrpc().AddServiceOptions<MyService>(options =>
    {
        options.MaxReceiveMessageSize = 2 * 1024 * 1024; // 2 MB
        options.MaxSendMessageSize = 5 * 1024 * 1024; // 5 MB
    });

Enable server reflection

Reflection is helpful if we want to allow discovery of our gRPC definitions from tools like Postman. To enable it:

• install X NuGet package
• builder.Services.AddGrpcReflection()

To test it: Open Postman ///TBA
